ComposablePrinter class

A LogPrinter that formats records through a composable decorator pipeline.

Construction

decorators are applied to a fresh LogStyle at construction time. The resulting style is immutable for the lifetime of the printer — mutation after construction is not supported.

Pipeline

LogEntry
  → ContentExtractor.extract()   (parse sections, className, methodName)
  → StyleResolver.resolve*()     (map LogStyle flags → ResolvedStyle)
  → LogRenderer.render()         (assemble lines)

Output

output defaults to print and can be overridden for testing.
